For what it's worth I'm sitting with two of my asian friends, who agreed with the quoted sentiment, so it's definitely not just "middle-to-upper-class white males" who hold these views.
I also know I'd think very little of someone who tried to dismiss a viewpoint of mine with something that amounted to "of course you'd think that, you're Arab*
In the current climate, it is acceptable to make broad generalizations about white males, however if the same exact generalizations are made about black people, then they will call you racist (Black Lives Matter), or if you make the same exact generalizations about trans or non-binary people, you will also have problems. I don't think they are anti-Arab anymore, they lost interest in the War on Terror because it wasn't working. Instead, it looks like they are moving to demonize the Russians and the Chinese. Obviously, the climate will change at some point.
Moving to? You've just described the bipartisan position of the US for the past 20 - 40 years.
They want me to unlock my phone and give it to them, I do it. I then file a claim with apple care and get a new phone because I pay $10 a month for theft protection.
Use common sense, don’t live your life in fear
